Hi all,

Sorry for the delay, I don't have much time to work on kisskb these days :}

I've updated things to work. It required a bit of fiddling because the
cross compilers I use from kernel.org don't have hppa and hppa64 in the
same prefix. But I just rsync'ed them into a shared directory and that
seems to be working.

The two parisc configs we have are here, everything recent is green:

  http://kisskb.ellerman.id.au/kisskb/config/507/
  http://kisskb.ellerman.id.au/kisskb/config/508/

I also added gcc11 for parisc.

cheers
